Leftover fluid in Ovidrel trigger shot

Gurpie

Okay guys so it’s my first cycle with Letrozole, trigger shot, times intercourse and Prometrium!

And my first time with the trigger shot!!

So I gave myself the trigger shot and I pushed the button all the way and it did turn all the way to 0 on the canister but then there was a tiny bit of fluid left inside the needle. I held it in for 5 seconds to make sure lol the medicine goes in. I couldn’t give the rest of the fluid to myself after I took it out because I know the needle tip is blunt and it’s going to hurt and I’m not about to reinsert the same needle into me again for risk of infection but does anyone have any experience with this. Because I know I got the push thing down to 0 I saw it there so I’m confused

Is this okay ? Does anyone have any experience with this that could help me
